Question

State any two reasons to prove landfills are not environment friendly.

Answer 1

Landfills are not environment friendly because of the following reasons:

1. Landfills release methane, carbon dioxide, water vapour, trace quantities of oxygen, nitrogen, hydrogen and non-methane organic substances. If these gases are not controlled, they have the potential to contribute to climate change and produce pollution.
2. Furthermore, industrial and household cleaning products are disposed of in landfills as a toxic mixture. Rain occasionally washes these chemicals away, accumulating them and possibly transporting them to municipal water systems, where they can contaminate groundwater.
